UPHOLSTERING-MACHINE Specification of Letters Patent.

Patented Aug. 17, 1909.

Application filed August 24, 1907. Serial No. 390,025.

To all whom 'it may concern:

Be it known that I, ISAAC KARPEN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Upholstering-lachines, of which the following is a specification.

My invention constitutes an improvement on the upholstering machine described and claimed in my application No. 390,024, filed of even date herewith.

My primary obj ect is to provide improved fastener-holding means for use in connection with a machine of the character indicated.

The invention is illustrated in the accompanying drawing, in which- Figure l represents a broken sectional view of a mold of a tufting machine having its presser-board, or follower, equipped with my improved fastener-holding means; Fig. 2, a similar view showing an edge-rail of the mold removed and the covering of the mattress, or pad, turned up for connection with the fasteners; Fig. 3, a broken edge view of the follower with the improved fastenerholding means applied thereto and fasteners held thereby; Fig. et, a perspective view of one of the fastener-guides employed; and Fig. 5, a broken perspective view of the follower and one of the retainer-bar guides employed.

In the drawing, A represents the mold of a tufting-machine, having a bottom A1 and a removable edge-rail A2; B, the follower of the mold; and C, my improved fastenerholding means applied to the edge of the follower.

The fastener-holding means C comprises vertically disposed fastener-guides c having attaching flanges 01 at their upper and lower ends and provided with T-slots c2 for receiving the fasteners c3,- retainer-rods c4x adapted to cross the open channels of the T-slots and spaced to receive between them the shanks of the fasteners; and retainerrod-guides c5 applied to the edge of the follower-board, as by screws c6, said guides c5 being provided with horizontal channels c7 disposed to space the rods so as to accommodate the shanks of the fasteners. The upper and lower margins of the followerboard B are recessed to receive the ianges c1 of the members c and said members are secured to the board by screws 0S.

As described in the above-mentioned application, the heads of the fasteners are received in the guides c, the points projecting outwardly. One retainer-rod is withdrawn to permit the fasteners to be dropped into their guides, after which said rod is inserted to secure the fasteners in place. D represents a mattress, or pad, (inverted during tufting) having an inner fabric (usually canvas) d, an outer covering (usually leather or imitation leather) (Z1, and a fringe or flap cl2. As is known, the margins of these fabrics are preparatorily perforated to receive the fasteners. After the fasteners are entered and clenched, the lower retainer rod is withdrawn and the follower' is lifted from the pad.

In practice, the members c are formed from sheet-metal, and the members 05 are cast. It is observed that the members c5 and their channels are deep enough to permit the rods c* to lie outside or across the members c.

Vhat I regard as new, and desire to secure by Letters Patent, is

1. In means of the character set forth, the combination with a follower, of sheet-metal members formed with T-slots therein and equipped with means for attachment to an edge of the follower, retainer-rods crossing said slots, and guides for said retainer-rods applied to an edge of said follower.

2. A fastener-guide clip for the purpose set forth, comprising a member adapted to extend cross-wise of the edge of a followerboard and formed with a T-slot therein and with attaching flanges at its ends.

ISAAC KARPEN.
